341 Live Audio Effect Reference

Normally, the signal being processed and the input source that triggers the device are the same

signal. But by using sidechaining, it is possible to apply dynamics processing to a signal based

on the level of another signal or a speciﬁc frequency component. To access the Sidechain pa-

rameters, unfold the Multiband Dynamics window by toggling the button in its title bar.

Enabling the Sidechain button allows you to select any of Live’s internal routing points from the

choosers below. This causes the selected source to act as the device’s trigger, instead of the sig-

nal that is actually being processed.

The Gain knob adjusts the level of the external sidechain’s input, while the Dry/Wet knob al-

lows you to use a combination of sidechain and original signal as the trigger. With Dry/Wet at

100%, the device is triggered entirely by the sidechain source. At 0%, the sidechain is effectively

bypassed. Note that increasing the gain does not increase the volume of the source signal in the

mix. The sidechain audio is only a trigger for the device and is never actually heard.

The headphones button allows you to listen to only the sidechain input, bypassing the device’s

output. Since the sidechain audio isn’t fed to the output, and is only a trigger for the device, this

temporary listening option can make it much easier to set sidechain parameters and hear what’s

actually making the device work.

22.22.4 Multiband Dynamics Tips

Multiband Dynamics is a feature-rich and powerful device, capable of up to six independent

types of simultaneous processing. Because of this, getting started can be a bit intimidating. Here

are some real-world applications to give you some ideas.

Basic Multiband Compression

By using only the upper thresholds, Multiband Dynamics can be used as a traditional ”down-

ward” compressor. Adjust the crossover points to suit your audio material, then apply downward

compression (by dragging down in the upper blocks in the display or by setting the numerical

ratios to values greater than 1.)

De-essing

To remove ”harshness” caused by overly loud high frequency content, try enabling only the

upper band and setting its crossover frequency to around 5 kHz. Then gradually adjust the

threshold and ratio to apply subtle downward compression. It may help to solo the band to more
